Embodiment
To be described in detail the embodiment of the invention now, its example shown in the accompanying drawings, wherein, identical label is represented same parts all the time.Below with reference to the accompanying drawings embodiment is described to explain the present invention.
Fig. 1 illustrates the circuit diagram that is used for power factor correction (PFC) equipment of three-phase inverter according to embodiments of the invention.
With reference to figure 1, the PFC equipment of three-phase inverter comprises: rectifier 20, switch element 30, first current detector 40 and controller 50.Each of 20 pairs of three phase mains 10 of rectifier (that is, R, S, T phase AC power supplies) carried out rectification mutually.Switch element 30 is connected to the output of rectifier 20, and carries out the PFC switching manipulation with the voltage signal of the output signal that do not produce rectifier 20 and the phase difference between the current signal.First current detector 40 is connected to the common potential end of switch element 30, thereby this current detector detects the current signal that produces by the PFC operation.Controller 50 control PFC operations, thus this controller can make the phase place of the Phase Tracking phase voltage signal of phase current signal.
In three phase mains 10, three sinusoidal currents with same-amplitude and frequency at the three-phase with 120 ° of phase differences (promptly, R, S and T are mutually) go up and flow, and the N phase ground connection that each central point of three-phase (R, S, T) is gathered together, thereby three-phase and four-line distribution scheme is normally used for three phase mains 10.
Switch element 30 can comprise and is connected respectively to R, S and T three the IGBT switches 31,32 and 33 mutually that connect with the output of rectifier 20.
The reactor 11,12 and 13 of power factor that improves rectifier 20 is between three phase mains 10 and rectifier 20, thereby reactor 11,12 and 13 is connected respectively to R, S and T mutually.Zero-crossing detector 60 not only is connected to one in reactor 11,12 and 13 the input (for example, the T phase) mutually, is also connected to the N phase, thereby zero-crossing detector detects the zero crossing of input phase voltage and to the detected zero crossing of controller 50 outputs.
Therefore, controller 50 is connected switch element 31,32 and 33 at the zero crossing of the phase voltage that detects by zero-crossing detector 60.Section was after the past at the fixed time, controller 50 uses pulse-width modulation (PWM) control method cut- off switch element 31,32 and 33, maintained switch element 31,32 and 33 off-state are up to the zero crossing that arrives next phase voltage, thereby carry out can correcting power factors the PFC operation, to prevent the phase difference between phase voltage and the phase current.
In this case, controller 50 determine whether to exist based on the current value of first current detector 40 mistake of product with high current power environment and big electric capacity inverter the PFC operation (as, phase current postpones), thereby controller 50 can detect wrong PFC operation, and the current value of this wrong PFC operation expression phase current and use lags behind phase voltage pro rata.In other words, if determine to produce such faulty operation, postpone from the zero crossing of phase voltage the turn-on time that then is used for the switch element 31,32,33 of PFC operation, thereby controller 50 is carried out the optimized switch operation to realize the little phase difference between phase voltage and the phase current, and power factor is improved.
Power factor correction (PFC) equipment according to the three-phase inverter of the embodiment of the invention comprises: direct current chain voltage generator 70, inverter 80 and second current detector 90.Direct current chain voltage generator 70 is connected to the output of rectifier 20, thereby produces the direct current chain voltage of the power factor with improvement.Inverter 80 is connected to direct current chain voltage generator 70, is three-phase alternating voltage with the direct current chain voltage transitions that produces, and to motor 81 transmission three-phase alternating voltages.The load current that provides to motor 81 (that is) amplitude, phase current, and the load current amplitude that detects to the transmission of modulus (AD) transducer are provided second current detector 90.
Therefore, controller is according to the duty ratio of the amplitude control pwm signal of the load current of second current detector, 90 detections, this pwm signal control switch element 31,32 and 33.
Below describe above-mentioned three-phase activity coefficient adjustment (PFC) equipment and control method thereof in detail.
With reference to figure 1, if three phase mains 10 is applied to PFC equipment, then the three phase mains 10 as R, S and T cross streams power supply signal is applied to reactor 11,12 and 13, and the every cross streams power supply signal in R, S and the T cross streams power supply signal is applied to rectifier 20, thereby carries out rectification by rectifier 20 couples of R, S and T cross streams power supply signal.
Voltage by rectifier 20 rectifications is applied to direct current chain voltage generator 70, thereby direct current chain voltage generator 70 produces the direct current chain voltage that drive motor 81 needs.Provide the direct current chain voltage that produces from direct current chain voltage generator 70 to motor 81 by inverter 80.
Like this, when by three-phase inverter 80 when motor 81 provides direct current chain voltage, owing to be applied to the phase voltage of reactor 11,12 and 13 and the phase difference between the phase current causes power factor to worsen.
Therefore, in order to solve the above problems, power factor correction (PFC) equipment according to the embodiment of the invention allows zero-crossing detector 60 to detect the zero crossing of the phase place zero passage of phase voltage, thereby the zero crossing that zero-crossing detector 60 detects to controller 50 outputs, wherein, zero-crossing detector 60 be connected in the input of reactor 11,12 and 13 any end (for example, T phase) and N mutually.The above-mentioned zero crossing that controller 50 orders second current detector 90 detects at zero-crossing detector 60 detects the amplitude of load current, and based on the load current amplitude calculating pulsewidth (being duty ratio) that detects, thereby controller 50 uses the PWM control methods to connect switch element 31,32 and 33 based on the pulsewidth of calculating.
If connect switch element 31,32 and 33, then be applied to linear increase of phase current of reactor 11,12 and 13.If by the PWM control cut- off switch element 31,32 and 33 of controller 50, the phase current linearity that then is applied to reactor 11,12 and 13 reduces.
Like this, if the PWM by controller 50 controls the operation that switches on and off that repeats switch element 31,32 and 33, the phase current that then is applied to reactor 11,12 and 13 is followed the tracks of the phase place of phase voltage, and improves power factor in the mode of implementing the PFC operation simultaneously.
But, if use product in above-mentioned PFC operating period with high current power environment and big electric capacity inverter, then the electric current of phase current and use lags behind phase voltage pro rata, thereby need come power factor correction (PFC) control of correcting power factors by any delay PFC switching manipulation.Be described in detail below in conjunction with Fig. 2.
Fig. 2 is the flow chart that the PFC control method that is used for three-phase inverter according to an embodiment of the invention is shown.
With reference to figure 2, in operation 100, in order to carry out the PFC operation, controller 50 uses PWM control to connect switch element 31,32 and 33 by duty ratio, calculates this duty ratio according to the load current amplitude that second current detector 90 detects.
In operation 102, for detect any faulty operation of producing by the PFC operation in PFC operating period (as, phase current postpones), after switch element 31,32 and 33 is connected, first current detector 40 that is connected to the common potential end of switch element 31,32 and 33 detects the waveform (as shown in Figure 3 and Figure 4) of the current signal (being switching current) of potential end altogether, and exports the waveform of the current signal that detects to controller 50.
Therefore, in operation 104, controller 50 at the fixed time the section (promptly, about 1 minute) during check the current waveform of the common potential end that detects by first current detector 40, so that controller 50 determine whether to exist the electric current of mistake be repeated pre-determined number or more times (as, 10 times or more) phase current postpone.When PFC operating period when current signals flowing has the peak value of reference value at least in the opposite direction with the side of phase voltage, produce wrong current signal.If along with the side of phase voltage in the opposite direction the peak value of current signals flowing pre-determined number appears at least, then determine to occur phase current and postpone.
Fig. 3 illustrates the oscillogram of PFC switching manipulation when not postponing according to an embodiment of the invention in phase current signal.Fig. 4 is the oscillogram that illustrates according to the PFC switching manipulation when postponing phase current signal of the embodiment of the invention.
As shown in Figure 3, if do not postpone in phase current signal, then the current waveform of the common potential end of first current detector, 40 detections flows along the direction identical with the direction of phase voltage, and begins the PFC switching manipulation at zero crossing.
Otherwise as shown in Figure 4, if phase current postpones, then flow in the opposite direction with the side of phase voltage in the current waveform edge of the common potential end of first current detector, 40 detections, thereby can not begin the PFC switching manipulation at zero crossing.In this case, the phase difference between voltage and the electric current increases, thereby because the PFC operation causes power factor further to worsen.
Therefore, if generating phase current in operation 104 postpones, then in operation 106, controller 50 from the zero crossing of phase voltage with the PFC switching manipulation (promptly, the turn-on time that is used for the switch element 31-33 of PFC operation) postpones PFC switching manipulation time of delay (as shown in Figure 5), and carry out best PFC switching manipulation, thereby improve power factor with the very little phase difference of generation between phase voltage and phase current.In this case, postpone (that is PFC switching delay time) turn-on time of prescribed switch element 31-33 in controller 50.Postpone expression each turn-on time and have the exemplary time that phase place consumed identical with phase current signal up to phase voltage signal.
In operation 108, controller 50 determines whether pass by the scheduled time after postponing the turn-on time of switch element 31-33.In operation 110, controller 50 is to postpone the turn-on time that preset time automatically reduces switch element 31-33 at interval.In this case, also in controller 50 turn-on time of prescribed switch element 31-33 postpone (that is, PFC switching manipulation time of delay).Postpone expression each turn-on time and have the exemplary time that phase place consumed identical with phase current signal up to phase voltage signal.
In addition, in operation 112, in order to postpone the turn-on time that reduces switch element 31-33 with preset time at interval continuously, controller 50 redefines the phase current that whether occurs by postponing turn-on time that reduces of switch element 31-33 to cause to postpone, thereby controller 50 is observed the performance of the PFC operation that the delay by phase current causes continuously.
As clear from the above description, use the operation of the mistake of the current sensor senses three-phase inverter that is positioned at common potential end according to the PFC equipment in the three phase mains of the embodiment of the invention (that is three-phase PFC equipment).In this case, since the delay of the input current signal of three-phase inverter, the operation that in the PFC operation that realizes power factor correction (PFC) based on the switch controlling schemes, may make a mistake.So if input current postpones, then above-mentioned three-phase PFC equipment is from the turn-on time delay scheduled time of input voltage zero crossing with each switch element, and carries out input current and postpone the optimized switch operation that causes, thereby realize increasing power factor.In addition, postpone the turn-on time that automatically reduces switch element with preset time at interval, thereby PFC equipment is observed the PFC performance serially.
Though represented and described embodiments of the invention, it should be appreciated by those skilled in the art that under the situation that does not break away from the principle of the present invention that limits its scope by claim and equivalent thereof and spirit, can make amendment to embodiment.
